Dry-type power transformer SCB distribution transformer

     Dry-type power transformers are a type of dry-type transformer with high electrical strength, mechanical strength, and thermal resistance. They are products designed for urban grid renovation and are particularly suitable for important locations such as high-rise buildings, airports, power stations, and commercial centers that require fireproof, explosion-proof, and moisture-resistant features. The core of dry-type power transformers is made of high-permeability grain-oriented cold-rolled silicon steel sheets, with a 45° full斜步进接缝. The core adopts a special square tube pull-plate structure, and the core columns are bound with insulating tape. The core surface is coated with special resin to prevent moisture and rust, effectively reducing no-load loss, no-load current, and core noise.

Product Features:

1. Low loss, excellent energy-saving effect, providing economic benefits in operation.

2. Flame-retardant, explosion-proof, pollution-free, maintenance-free, and can be distributed and installed at load centers, reducing investment costs and saving expenses.

3. Partial discharge is less than 10PC, the coil does not absorb moisture or dust, has high mechanical strength, and good reliability.

4. Good resistance to short circuits and lightning impacts.

5. The enclosure is made of three materials: stainless steel, cold-rolled plate, and aluminum alloy. Types include air-draft type and heat dissipation type. Wiring can be top-in top-out, bottom-in top-out, or bottom-in bottom-out.

6. The transformer can be equipped with a temperature control and temperature display system as per user requirements and can be used in conjunction with a temperature control system.

Usage Conditions:

1. Altitude not exceeding 1000m.

2. Ambient Temperature

Maximum temperature: +40°C

Daily average temperature: +30°C

Annual average temperature: +20°C

Minimum temperature: -30°C (for outdoor transformers)

Minimum temperature: -5°C (for indoor transformers)

3. Waveform of Power Supply Voltage

The waveform of the power supply voltage should approximate a sine wave.

4. Symmetry of Multi-phase Power Supply Voltage

The power supply voltage connected to multi-phase Satons transformers should be approximately symmetrical.
